Product Description
Human Factor XII
Purified from fresh frozen human plasma. Human Factor XII is part of the contact activation system. Human Factor XII is a single chain glycoprotein with a molecular weight of about 80,000. Once activated, principally from the action of kallikrein, Factor XII is converted into an active serine protease (Factor -Xlla) that functions in the in vivo initiation of blood coagulation, fibrinolysis, and kinin formation. Purity of Factor XII is >95 percent by SDS-PAGE and activity is determined via clotting assay. Prepared from plasma found negative by FDA accepted methods for Anti-HIV1/2, Anti-HTLV I & II, HBsAg, Anti-HCV, Syphilis, HBC Ab, HIV-1 p24 Ag or HIV-1 RNA, HCV RNA and HBV RNA. Donors are screened for CJD (Creutzfeldt-Jakob Disease).
